HI, my friends:
now, i am USING ABB PLC -"Scattcon 35" ,have the software DOX10
my question is the word variable "AS" ,have the function analog status ,range from AS0--AS4. but i am not sure the detail function used in the system.
in my opinion ,when the 4--20mA analog signal failure above high limit or below low limit,etc.then the word assigned value
i am not sure my opinion is right
please my friends give me the right answer
thanks in advance
